Don't overload functions by return type. This is generally a bad idea. If designs.orthogonal_array doesn't return some kind of array then it is poorly named. Use three different functions, e.g. orthogonal_array() / is_constructible() / size_of_array()
This basic design pattern also fixes your caching problem.
